By heating tobacco instead of burning it, these products create aerosoloffering the flavour and ritual many smokers enjoy, without the smoke, ash, and many of the by-products of combustion

When a belt slips or rubs against the roller, friction increases, generating heat that can produce visible smoke
Carbon Filter: The Al Capone Cigars incorporate a Carbon filter which has a very high surface area resulting in excellent absorption of the tar as the smoke passes through without affecting draw or flavour for a smoother cleaner tasting smoke
CVS notches about $1.5 billion annually in tobacco sales, but it expects the $2 billion drop in revenue from phasing out tobacco because smokers often buy other products when they visit their stores
